I am trying to configure FreeBSD 4.6.2 to bring up my sound system in a 
notebook. First, I tried using kldload /modules/snd_neomagic.ko but then 
I don't know what to do later. I searched at lot on FreeBSD website and 
google without success about dynamic load. So I go re-compile the kernel.

Before I made a compiling I did check "dmesg" and found no "pcm" string. 
Seems that the probe couldn't detect this sound chip as a pcm device. 
However, it detected and found

.......
chip1: <NeoMagic MagicMedia 256AX Audio controller> at device 0.1 on pci1
.......

I follow the guidance of sound manual on FreeBSD website. Using the 
GENERIC config file, copied it to MYKERNEL and did stuffs; conf 
MYKERNEL, make depend, make, make install... etc. I could do without 
error and reboot. Now I check again dmesg.

........
pcm0: unable to map register space
chip1: <NeoMagic MagicMedia 256AX Audio controller> at device 0.1 on pci1
.........

appear in dmesg.

Please help me... please give me a suggestion how to deal with this 
problem...

My system is...
A notebook... Panasonic CF-M2
PIII class CPU on 440BX chipset + Neomagic 256AV/ZX SVGA and sound
